Abstract: A retention system is provided for use in connecting a replaceable tool to a work implement. The retention system may have a generally cylindrical pin with a first hollow end, and a second hollow end located opposite the first hollow end. The retention system may also have a first fastener configured to engage the first hollow end and cause the first hollow end to flare radially outward. The retention system may further have a second fastener configured to engage the second hollow end and cause the second hollow end to flare radially outward.

Abstract: A pin for use in a dynamic pin joint is provided that comprises a core member that defines a longitudinal axis and an outer diameter and a self-lubricating material overlay that is disposed about the outer diameter of the core member along at least a portion of the longitudinal axis of the core member.

Abstract: A linkage pin joint assembly may include a portion of a first machine member having a first bore, a portion of a second machine member having a second bore, and a linkage pin pivotally interconnecting at least the first and second machine members. The linkage pin may extend between the first and second machine members, and be positioned at least partially within the first bore of the first machine member and the second bore of the second machine member. The linkage pin may extending at least partially through the first and second bores and pivotally support the first and second machine members relative to each other.

Abstract: An elastomeric bushing can be incorporated into a pin joint assembly of a machine. The elastomeric bushing can be configured to allow at least three degrees of relative rotational movement, including roll, pitch, and yaw. The elastomeric bushing can rotate with respect to a pin about a longitudinal axis thereof. The elastomeric bushing is adapted to accommodate out-of-plane movement. The elastomeric bushing can include a plurality of alternating elastomeric layers and metal plies.

Abstract: A floating pin joint assembly pivotally connects a lift arm between spaced frame members. The lift arm includes a bushing with bearing surfaces supported on the pin for relative movement. Extending end portions of the pin are supported on bearing surfaces defined by collars connected to the frame members by inserts press fit into the frame members. Removable cover plates connected to the inserts contain the axial movement of the pin and permit removal of the pin and other components from the assembly. The load bearing surfaces are disposed within a lubricated chamber extending between the cover plates.

Abstract: A method of verifying proper coupling of an implement assembly to a lift arm assembly by an operator who is located in a cab of a work machine is disclosed. The work machine includes the implement assembly and the lift arm assembly. The implement assembly includes a hinge plate. The hinge plate has a first coupling aperture extending therethrough. The lift arm assembly has a lift arm and a cylinder. The cylinder is secured to the lift arm. The method includes the step of actuating the cylinder so as to move a pin from a first pin position to a second pin position. The pin is spaced apart from the first coupling aperture when the pin is located in the first pin position. The pin extends through the first coupling aperture when the pin is located in the second pin position.

Abstract: A linkage assembly for connecting an implement to a frame of a work machine which provides greater visibility for an operator of the work machine is disclosed. The linkage assembly includes a box-boom lift arm having a frame end portion and an implement end portion, wherein (i) the frame end portion is pivotally coupled to the frame, (ii) the implement end portion is pivotally coupled to the implement, and (iii) the frame end portion includes a first extension and a second extension spaced apart from each other so as to define a first lever space therebetween. The linkage assembly also includes a lift cylinder having a frame end and a lift arm end, wherein (i) the frame end is pivotally coupled to the frame, and (ii) the lift arm end is pivotally coupled to the box boom lift arm. Moreover, the linkage assembly includes a rear tilt link having a first end and a second end, wherein the first end is pivotally coupled to the frame.

Abstract: A lift assembly for lifting an implement relative to a frame of a work machine is disclosed. The lift assembly includes a lift arm having a frame pin bore, a cylinder pin bore, a linkage pin bore, and an implement pin bore. The frame pin bore and said cylinder pin bore define a first line. The frame pin bore and said implement pin bore define a second line. The second line is located above said first line. The first line and said second line define an angle which is greater than three degrees. A plane intersects said first line at a center point of said cylinder pin bore and is normal to said first line. A said plane divides said lift arm into a frame-side segment and an implement-side segment. The first line includes a first segment which is entirely coincident with said implement-side segment of said lift arm. The linkage pin bore is defined in said frame-side segment. The lift assembly further includes a tilt lever which is pivotably coupled to the lift arm at said linkage pin bore.
